LeTV FF91 accelerates the new king every 100 kilometers, and the new record of the fastest production car is about to be born! Look at the world's top luxury cars, the world's most cattle super run, the fastest electric SUV on the surface how to break through the 2.39 seconds.
Appearance, this LeTV FF91 is really amazing, the futuristic shape does not lose Tesla, the texture of carbon black matte is comparable to the Porsche Cayenne.
LeTV FF91 is absolutely satisfying. In fast charging mode, it only takes 1 hour to charge, and it can last for 500 kilometers. The maximum cruising range is up to 700 kilometers. At the same time, it also supports household 220V voltage charging.
LeTV FF91 length and height are 5250/2283/1598mm, the wheelbase is 3200mm, so the size is more than a large SUV?
LeTV FF91 zero to 97 km / h acceleration time is 2.39 seconds, the current SUV field should be the fastest acceleration model, not to mention SUV, that is, super-running is not faster than it is faster than it
With the rapid development of wireless sensing technology, 433 MHz wireless communication devices have been more widely used in portable devices, vehicle-mounted terminals, intelligent locks and other fields [1]. As an important part of wireless communication equipment, antenna is a key component that affects the overall performance of the communication system [2].
Domestic and foreign scholars have been exploring the 433 MHz printed antenna with high gain and miniaturization for many years. However, there are two main trends in the design of 433 MHz printed antenna by previous scholars: one is to sacrifice size to ensure high gain, such as the structural scheme in literature [3]; The other is to sacrifice gain to ensure size miniaturization, such as the scheme in reference [4].
Taking into account the effective size and gain characteristics of the antenna is the difficulty in the design of 433 MHz miniaturized printed antenna. Based on the research experience of domestic and foreign scholars on 433 MHz printed antenna, a 433 MHz miniaturized spiral printed antenna is designed based on the 1/4 wavelength monopole antenna. The simulation results show that the antenna occupies only 20×35 mm2 and the effective gain is -4.14 dB.
